Schematic representation of the extracellular matrix (ECM). In a natural environment, cells (green) use specific markers (pink) to bind to a mechanical support matrix of polysaccharides or hydrogel (yellow) and fibrous proteins (blue). Dissolved proteins like growth factors (purple) enable communication between the cells and matrix-degrading enzymes (black), thus remodeling the matrix [67]
